Françoise Beaucournu-Saguez

Beaucournu-Saguez published many studies on the blackflies (simuliids) of western Europe, North Africa and the Middle East from 1972 to 1992) with much of her research resulting from her personal fieldwork in France, Spain, Portugal and Morocco.[1][2] According to an obituary,

It is to her that we owe the first discovery that the female of Simulium velutinum can be distinguished from that of other European species of the S. aureum group (= Eusimulium s. str.) by lacking the usual pigmented “nipple” on the spermatheca at the base of the duct1 - a character that has proved constant and very reliable for recognizing this species among otherwise inseparable females.[1]

Her research was well known for her formal taxonomy of the Palaearctic realm, especially her descriptions of Levitinia freidbergi from ephemeral streams on the Golan Heights in Syria under Israeli Military Administration (done with Dr Yehuda Braverman who collected the studied specimens)[1]

Blackfly (simuliid)

In her later years, she worked in northwest France and was associated with the Department of Parasitology and Applied Zoology at the University of Rennes.[1][3]

She was married to the parasitologist Jean-Claude Beaucournu (born 1934) who specialized in fleas (Siphonaptera) and who was a co-author on some of her blackfly research.[1]

Beaucournu-Saguez died on 11 August 2000.[1]

Her research is published under two different names: Beaucournu-Saguez, F., and Saguez, F. B.
